Sintes OLIVER E. GREENE'OF LAWRENCE, MASSACHUSETTS. Letters Patent No. 89,038, dated .April 20, 1869.

The Sahdule refened to 1n these Letters Pat-ant and making part of the snm To all whom it moy concern A l `Be itV known that I, OLIVER E. GREENE, of Lawrence, Essex county, in the State of Massachusetts, have invented nu Improved Lubrie'iting-Device, which I call a lubricating-sleeve; and I hereby declmethe following to be afull and exact description thereof, reierence being had to the accompanying drawings, forniing part of this specification.

The nature or essence oi' my invention consists iu placing upon a shall, or axle, on which nloose pulley, or wheel is to turn, o. hollow cylindexg'or loose sleeve, so that the pulley, or wheel muy have this sleeve within it when placed upon the shatt, and may turn uponv it, or turn with it, :ts muy happen; also in niukiug a. number of holes, or slots in or through said sleeve, to facilitate lubrication.

1n the following descripcion ot' my invention, the

drawings `hereinbefore mentioned will be referred to,

Figure 1 being n view ofn fast pulley and loose pul-` ley 4ou the saine shalt, partly sectional, and

Figure 2, n view of the sleeve.

In these drawings- D is a sha, having on it the fast pulley B and the loose pulley O.

Within the hub of the pulley C is the loose sleeve A, occupying a. space between the hub or box and the shalt, and free to turn along with the pulley, or to turn somewhat slower than the pulley, or 'to relnnin stationary on the slintt while the pulley turns on it, according to the degree of friction between the different ports.

The pulley C has an opening, or passage, d, for the introduction of oil, -und the sleeve A is pierced with o number of holes, b b, directly under or opposite tothe passage. d, so that oil poured into this passage muy fill the: holes b, :ind spread between the sleeve and the shalt, nud between the hub :ind sleeve.

A number ot' slots, a a, is vmode in or through the sleeve, :it dierent points, to receive any surplus oil, so that instead ol' working out, it muy be held in reserve iu. these until wanted, when it will spread, and come into use.

The holes b will also perform the same oll, and as many slots or holes, or both, uiny he made in the sleeve as may be deemed necessary or useful.

' If-the shall, or axle be tapering, as is commonly the onse with marriage-axles, the interior of the sleeve should conform to the shape of the axle, and the exterior to the shape of the hub, or box, whether straight or tapering.

The foregoing being :i description of my invention,`

1 claim :t lubricating-cylinder, or sleeve, arranged between the shaft, or axle and the hub ofqthe pulley, or wheehnnd tit-ted to turn freely on the shell, and in the hub, subsuintially as described.

I also claim perfomting the cylinder, or sleeve, am-

mnged to turn freely between the shaft, or axle and the hub of the wheel, or pulley, substantially as described, for the purpose set forth.
